In the new book "The Dark Knight: Featuring Production Art and Full Shooting Script" (now available in bookstores and online) the millions of fans who have flocked to see this summer's box office king will find a special -- albeit twisted -- treat.

Along with storyboard art, person behind-the-scenes notes by Director Christopher Nolan and a ton of other materials that make this a must-have compaion book to the film, there's also a series of make-up tests for the Joker. Scans hit the web today, and believe us, if you thought the final product that showed up in the film was creepy, you ain't seen nothing yet! Check out one of the scans after the jump.
